Advice on Having a criminal record and getting into consulting or finance

Hello everyone, I'm seeking some advice and guidance regarding my situation and how it might impact my future career in the financial services industry. A bit of background about myself: I'm a 23-year-old student currently studying Accounting and Finance at a Top Ten University. I’ll be graduating at the age of 25, making me somewhat of a mature student. My journey to this point has been quite unconventional. When I was 18, I made a significant mistake that still haunts me. At the time, I was struggling to find a part-time job, and I knew a couple of people who were selling cannabis and making a bit of money on the side. It seemed like a good idea then, but looking back now, I realize how foolish it was and I take full responsibility for my actions. I ended up selling weed to my friends and people I knew. One day, I was caught by the police with around 13 or 14 grams of cannabis and multiple small plastic bags, which clearly indicated I was selling it. I pled guilty as I was caught red-handed. Consequently, I was convicted of possession with intent to supply a Class B substance. Since then, I’ve worked hard to turn my life around. After moving to a different city, I enrolled in university but ended up dropping out after a year to start a recruitment business. I successfully ran this business for two years before selling my shares to my business partner. Now, I’m back at university, committed to building a career in finance, with dreams of working in investment banking, retail banking, commercial banking, private equity, asset management or Consulting. My concern is that this criminal conviction, which occurred when I was 18, will jeopardise my chances of achieving my career goals. By the time I graduate, seven years will have passed since the conviction, but I'm worried it may still affect my employability in the finance sector. Has anyone else been in a similar situation or know of someone who has? How might this past mistake impact my future opportunities, and is there anything I can do to mitigate its effects? Any advice or insights would be greatly appreciated.
